To all whom it mag concern: 3 Be it known that I, ELEAZAR PARMLY, J rl,

a citizen of the United States of America, residing at Washington, in the District of 5 Columbia, have invented certain new and useful Improvements in Ehbulatir g,- Back- Spacing, and Key-Connecting Mechanism,

of which the following is'a specification. My present invention relates to a combined tabulating, back spacing and key 0on1 'ncoting mechanism primarily designed tor the equipment of a combined typewrltlng "and adding machine.

The bject of the invention is to equip a writing-adding machine with a mechanism operativ'e'to retract the carriage across'the adding field, to set a tabulating stop inpo" *gsition to arrest the carriage at the proper 'point for the printing of the next number when the carriage is again moved forward.

' to connectlthe keys of the typewriter with the adding mechanism, 'and'to release-the carriage for free forward 'movcment with the stop mechanism andthe key connecting mechanism in operative position; 3 7

Other objects of the inventionviewed-invarious aspects will appear as the s-ucceeding description progresses.

The EZliottsFisher ventlon applied theretojs what is known as the Elliott-Fisher billing-adding machine,

a combined typewriter-and adder of the downwardly printing orflat -platen type.

The typewriting machine includes a fiat platen 1 over which travels longitudinally for line spacing a machine .frame2, support:

ing a carriage 3 which travels transverselyof the platen for letter spacing and supports downwardly acting printing mechanism -1 operated from the numeral keys 5 of the typewriter. The carriage 3 is propelled in the direction of letter spacing by carriage propellin mechanism, not shown, and is controlle' by an escapement 6 operated from the keys 5 to permit a step-by-step advance ofthe carriage. For a more complete description of the machine than is considered necessary for the purpose of this disclosure, reference is made to Patent No. 573,868 to R 3. Fisher, The tabulating mechanism.-The Elliott- Fisher' typewriter is'commonly equipped with a'tabulating "mechanism bymeans of Patented J n. '3o; 1912. Application filed April 16), 1909. Serial No. 489,192.

balm -addin ma chipe.--The machine illustrated inthe ac-' companying drawings with my present inwhich the carriage of the machine may be released for free movement and arrested in any desired denominational relation to a predetermined point, as for instance the declmal'point of the column. .This mechafinism includes a pin rail 7 extended along the front of the frame-2 and haying a-series' of pin sockets 8 in anyone of which a fixedstop or pin fl msy be placed.

, Mounted .to slide in suitable guides at the right hand end of the carriz'i s3 is a movable stop member in the'form 0 a plate 10, the front edge of which is dis osed at an angle will with respectto the plane 0 movement of the carriage. and 15: formed with a series of stepped stops 11. The plate 10 normally occupies a position which presents it out of interfring relation with the fixed stop 9, see .Fig. 1, so that the latter opposes no obstruction to the free movement of the carriage. hen, however, it is desired to arrest the carriage by means of the tabulating mechanism, the plate 10 is advanced so that, as the carriage advances one of the stops 11 will engage the fixed stop 9. It is obvious that the relation of the carriage to the fixed stop 9 when arrested is determined by the degree of forward movement of the plate 10 and the particular stop 11 thus selected for cooperation with the fixed stop 9.

To facilitate the mani ulation of the plate 10 the latter is provide along its left hand edge with a rack 12 engaged by a inion 13' suitably journaled on the end wal of the carriage 3. The pinion 13 in turn meshes with a toothed segment 14 formed on a disk 15 journaled on a hollow stud 16 screwed into the end wall of the carriage casing, as shown in Fig. 2. The disk 15 is adapted to be oscillated by a tabulator lever 17 fulcrumed at its lower end upon a post 18 outstanding from the disk 15 adjacent to the .griphery of the latter. At a point diametrically opposite the post 18 the disk 15 is provided with a lever guide 19 bifurcated to receive the lever, as shown in Fig. 2. This character of mounting of the actuator lever 17 compels the disk to move therewith when the lever is swung forward or back with the axial bearing of the disk as a fulcrum, but

enables the lever to be moved laterally with its mounting in the post 18 as a fulcrum. When the lever 17 is swung forward the disk 15 is rotated an" motion is thus imparted to the pinion 13 and the stop plate 10, the latter being projected toward its active or 0perative position. This forward movement of the plate '10 is resisted by a retracting spring 20, see Fig. 1, having connection at its rear end with a fixed part and at its front end with the plates, the shock incidental to the retraction of the latter being absorbed by a cushion 21 with which a pin 22 on the plate 10 contacts. hen the stop plate 10 is advanced to its active position, it is customary to effect the release of the carriage from' the control of the'cscapement so that the carriage may move forward until arrestedby the coaction of the stops 9 and 10. To accomplish this a bell crank release dog 22 is mounted inside the carriage casing at the right hand end thereof and its horizontal arm overlies the release lever 23 of the carriage release mechanism which also includes a release key 24 connected to the front end of the lever 23 and by means of which the carriage is released for free-mowing}? when the tabulating mechanism is not employed."

The vertical arm of the release dog 22 is opposed to the inner end of a'sliding release pin 25 fitted axially in the bearing 16 and opposed at its outer end to the short arm of a sub-lever 26 fulcrumed on the tabulator lever 17.

Associated with the lever 17 is a combined guide and index plate 27 curved concentric to the axis of the disk 15 and having a slot 28 for the accommodation of the lever 17 as the latter is swung forward and back. At one side of the slot the plate 27 is provided with an index 27 bearing denominational indications as for instance from 1 to 100,000,000. and opposite these indications the late is provided with notches 27 to facilitate the accurate sitioning of the tabulator lever 17 when tl i latter is moved forward to any desired denominational position. A second sub-lever 29 is mounted on the lever 17 and has an angular end 29 interposed between the edge of the ide plate 27 and the upper free end of the ever 26, see Fig. tn- A5 a result of this arrangeinward to operate the release dog 22 which in turn operates the release lever 23 to release the carriage and permit the latter to advance freely until j arrested by the con-' tacting of one of the stop faces 11 with the stop pin 9.

The back spacing mechahism.The back spacing mechanism includes a back spacing member in the form of a cam plate30 imposed uponthe stop late 10 and haying an angular front end wiich constitutes a cam 30 adapted to coact with a fixed part, as for instance the pin 9, which, in order to reduce a the friction incidental to such coaetion. is provided with an anti-friction roller 31 with which the cam 30 engages. In the normal position of the stop plate 10 and the cam plate 30 the latter occupies a relatively advanced position, so that if the two plates are projected in unison, the cam 30 will contact with the roller 31 and cam the carriage back until the stop plate 10 is located at theleft of the stop 9 before said stop plate has been projected into interfering relation with said stop. To cause this simultaneous forward movement of the two'plates 10 and 30, they are normally coupled by a coupling pin 32, see Fig. 1, extended through the plate 30 and into a socket 33 in the plate 10. At its upper end the pin 32 f. is pivotally connected to a trip lever 34 fulcrumed at its rear end '11 ou astud 35 upstanding from the cam p ate 30. The lever 34 is normally held in depressed position by a spring 36 of any suitable form and the front end of said lever is elevated somewhat to permit the post 18 pass thereunder when the upper end of the tabulator 17 is in a forward position:

By reason ofthe connection between the plates and 10 formed by the coupling pin' 32, said plates willbe: advanced H1 unison 'when'' the tabulatgr lever 17 is moved from its normal position, shown'in Fig. 1,;to an intermediate position. This forward move- ,ment of the tabulator lever 17 will cause the plate 10;

cam plate .30 to coact with the roller31 and cam the carriage back across the column andwill present the tabulator lever adjacent to the upper-end of the index27f andthe post 18 under the front end of the trip lever 34:. At this, point inthe movement of the tabnlator lever-it is necessary retract the [cam plate outnf interfering relation with the roller 31 so that the subsequent forward movement ofthe carriage will not beobstructed. Therefore the-relation of the parts is such. that further forwardjniovement of the tabulator leverWill cause the 5 post 18 to rise, thus elevatin the frontend of the trip lever 34 and withdrawing the coupling pin- 32'from the socket in the stop The connection between the plates eing thus broken, the cam plate 30 is retracted'by a retracting spring 37 secured at 3 its front end to, the plate 30 and at its rear end to one of two bearingibraekets 38 ezZ- tended from the right. hand end of the carriage and accommodating both the stop plate and the cam plate, As the'forward movement of the lever 17 conti'nneathe stop plate 10 will continue to moveforwardim dependently of the cam plate untilftheselected stop face 11 is moved into position to engage the pin 9 when the carriagei's released.

Thus when the lever 17 finally id-Fig.1, to a position opposite the-hum. -dreds indication on the index plate 27.

plet'ej, =;"lisolosure chine; Y The. adolmg: 'rrtechem'sm.-As heretofore oi? this feature of themestated, the Elliott-Fisher. writing-adding machine is a combined typewriterand'adder.

A sufficient description of the typewriter for the purposes of the present disclosure has been given and it remains to describe 723,98? to' John A. Smith for a'more com briefly the adding mechanism, since the suitable support rear of the machine framewil is a? register or compntmg devicev 4.1 including a series of denominational marchers 4:2 and e itable carrying mechanism. One form of register adapted for this use is shown in Patent No. 825,494 to John A. Smith, but the particular register here shown is the subject of the co-pending application of Laganke and Smith, No. 308,279.

Mounted on the typewriter carriage is a master wheel or actuator 43 adapted to engage successive denominational members 42 as the carriage of the typewriter advances stcp-by-step across the column to which the register 41 has been appropriated. The master wheel 43 is operated from the numeral keys 5 of the typewriter throughsuitable operating connections each of which imparts to the master wheel a rotary movement corresponding in degree to the value of the particular numeral key operated. One of these operating connections is shown generally in Fig. 1 and it will be seen to include a lever 44 gearedto the master wheel shaft 45 and operated by a lever 46 fulcrumed at its rear end, as shown at 47, and I provided at.its front end with a depending link 48 adapted to swing back and fort-h. This movement of the link" 48 causes a lug 49 thereon to engage or disengage a notched pin 50 projecting from the stem 51 of the adjacent numeral key. I

For the purpose of swinging all of the links 48 forward to engage the same with the keys 5 an oscillatory key connecting yoke 52 is mounted in the carriage casing and comprises a rock shaft 53 having laterally disposed arms 54 between which is disposed a bar 55 received within longitudinal slots 56 in the links 48.

The mechanism last described, to-wit the master actuator 43 and the connections between the same and the several numeral keys 5, is part of the usual equipment of an Elliott-Fisher writing-adding machine and is disclosed in Patent No. 829,971 to Laganke and Smith, to which patent reference thekey connecting mechanism here shown is generally identical with that found in the specified machine the equipment of which heretofore has been in accordance with the disclosure made in Patent No. 863,232 to John A. Smith.

Within the carriage casing is mounted ll yoke operating lever 57 fulcrumed on a support 58 and having its front end in engagement with the bar 55 of the key connecting yoke 52. At the rear end of,the lever 57 is mounted an abutment roller 59 shiftable into and out of coactiverelationwith the front end of a secondary. lever 60, the rear extremity of which is extended through the rear wall of the casing to enga e a swinging arm 61 mounted in rear 0 the casing contiguous to what is knownin the art as the key connecting arm 62. By means of a connection 63 the arm 61 when depressed or swung down will depress the arm 62 and thus 0 erate the lever 60 and through the latter t e key connecting lever 57 which will swing the yoke 52 for the purpose of mov-- ing the links 56 into engagement with the notched pins 50 on the numeral key stems. I At the right hand end of the key connectinglev'er 61 is formed a cam 64 which rides under what is known as the register plate 65,- the latter bein a small flange or ledge extending forwar ly from the register 41 at the bottom thereof. This mechanism, towit that train of elements intermediate of the cam 64 and the yoke 52, is identical with the corresponding elements in the Smith patent last referred to, with the sole exgeption that the rear end of the lever 60 is urcated, as indicated at 60, and extends both over and under the roller 59 when the latter is in its rearmost or operative position. It may be stated, however, that in accordance with my )resent invention, the mode of operation oi this particular mechanism is somewhat ditferent from that described in the Smith patent as will hereinafter more fully appear.

I now come to a description of the essentially novel elements of the structure shown.

Secured to the right hand end of the shaft 53 of the key connecting yoke 52 is a crank arm 66 the wrist 67" of which is engaged by the bifurcated front end of a lever 67 ful- 10 cru med upon a stud 68 projecting from the right hand endwal-l of the carriage casing. The rear end of the lever 67 is connected by means-of a link 69 disposed vertically, as shown in Figs. 1, 2. and 4, and having its 5 lower end connected with a comparatively long lever 70 disposed a-lonside of the release lever 23 and fulcrume as indicated at 71'. The lever 70 underlies the horizontal arm of the bell crank release dog 22, see Figs. 2 and'4, and also underlies the release arm (l'of the unit stop a.

It will be seen from what h s been said that the structure illustrated this ap lication does not differ from that hereto dre proposed, except for the described modificatitiil of the rear end of the lever 60 and for the ilddition of the'cran'k arm 66, the levers Q 67 and 70 and the link 69. It will, nevertheless, be seen that the mode of manipulaquentpositioning of any tabulator lever 17 forward. This causes. -the back spacing-cam plate to be operated to retract the carriage across the column and the master wheel across the register and continued forwardanovement of the lever 17 causes the automatic release and retraction of the. plate 30 and thesubseone of'the stops 11 to coact with the pin 9 for the purpose of arresting the carriage in any selected denominational position of the column when the. carriage shall have been released and allowed to move forward, all as described in my application No. 489,191, heretofore referredto. lever 17 to retract the carriageand position the tabulating or carriage arresting? mechanism, the lever '17 is swung later. 1y from the 0st 18 as an axis. In my above recited app-ication this lateral movement of .the lever 17 releases the carriage 'for forward sis movement, since the inward movement of the pin 25 will cause the release dog 2 2 to operate the release lever 23 of the carriage release mechanism. In the present instance, however, this lateral movement of the tabulator lever 17 results in the performance of still another function, to-wit the connection of the nm'heral keys of the typewriter with the operating mechanism, of the register. Thus when the lever 17 isswungto the left, the consequent-.operation of the release dog 22 depresses the front ends of both the carriage release lever 23 and the lever Not the key connectin .mechamsm. Th1s operation of the lever 0 causes the latter to elevate the rear end of the lever 67 through the medium of the link 69 and swings the crankarm 66 which in turn rocks the shaft 53 and causes the key connecting yoke'52, of which said shaft is an element, to throw the links '48 forward-and into engagement with the stems of the numeral keys 5. By the manipulation of the lever 17 the operator has now cammed the carriage back-across the col- ..umn, positioned a tahu'lator stop, released the carriage for forward movement, and

connected the keys of the typewriter with.

Having thus manipulated the t the cam 64 on the lever 62-,

instead chiming;l plate 65 upon t ;tueregister e advance o the carrla e,

will be sufiiciently lowered to pass on er said plate. The released carriage will now move forward until arrested by the tabulator stops in proper position for the writing and adding of the next number. When' the carriage isIt-hus positioned the tabulator lever and the stop plate 10 flyhack to their normal positions, as usual, and incidental to this retraction-of the parts the key yoke 52 is released andwould likewise be retracted by .itsspring a; were: it not for the fact that 'the cam til on 'the lever fi2-having been depressed by the manipulatlon'of the lever 17 will have passed under the plate 65 and will 'now be held down by said plate as long as the printin point of the carria e is in the column and as long as the master wheel is opposite the register. The carriage hav ing now been properly positioned and the keys having been connected with the adding anechanism, the operator proceeds to write the number in the column and to accumulate the same in the register. As soon as the machine passes beyond the column, the cam 64 will ride out from under the right hand end of theregister )late 65 and the retractingfs'prinp w of the key connecting yoke will incidenta ly retract the yoke to disconnect the keys from the addin mechanism by withdrawing the links '48 mm engagement with the stems of the numeral keys. Thus it. will be seen that by the'manipulation of a single element, to-wit the tabulator lever 17, the carriage is retracted, the tabulating mechanism is positioned, the keys are connected with the adding mechanism, and the carriage'is released in order to permit its instant advance to the proper position for the writing of the next number.

If it is not desired to utilize the variabletabulating mechanism and the carriage retracting mechanism, the unit stop'key a may be depressed to position the unit stop a and simultaneously release the carriage and stop key a will not only swing' the stop a into a path obstructed by the pm 9, but will also depress the frontends or the carriage releaselever. 23 and the key connecting lever 70.

By the employment of the mechanism described, the manipulation of a writing-adding machine is materially sim lified and the s of operation increase --The possi bility of error is nthermore minimized because if it is desire 3:0 print. digits in the adding field without operating the register, as for instance in "writing in a heading or the like, it is not'neces'sary for the operator {tn .ldisconnect the keys from the adding other manner which does not involve thev manipulation of'the tabulating mechanism. This is true for the reason that the camfii on the keyconnecting arm- (it-instead of normally occupying a position which -will present'it to the plate 65, is elevated in accordance with 'my invention so that normally it occupies-the position shown in Fig. 6, which will' permit it to pass over the plate when the carriage moves forward unless the arm 61 has previously been thrown-down by the operation of the lever 17. It will appear, however, that should it be desired to use the machine for straight typewriting, as for instance tabulation without addition,

and to employ the tabulating mechanism to facilitate said work, the entire key connect? ing mechanism may be put out ofa'ction by simply withdrawing the roller 59 out of cooperative relation with the lever 60"b vthe manipulation of the total'key in the usual manner. 4

It is thought that from the foregoing, the construction, operation and advantages of my invention will be fully comprehended, but I wish to be understood as reserving the right to effect such modifications of the 1llustrated structure as may'come fairly within the scope of the protection prayed.
